To all whom it may concern/.-

, Be it known that I, CHARLES E. DAMERELL,

a citizen of the United States, residing 'at` Benson, in the county of Linn and State of Missouri, have invented certain new and useful Improvements in Road-Scrapers; and I do hereby declare the following to be a full, clear,

and exact description of the invention, suchv as will enable others skilled in the art to which itappertains to make and use the same.

The basis of this invention is a scraper for leveling and grading roads. T he device, in common with like implements, embodies in its structural organization va plate which is dragged over the road o'r surface to be graded and a foot or tail board for con trolling the position of theplate and adapted to have pressure applied thereto for holding the machine Inasmuch as the soil varies in character in different locations, being stiif in some sections and light and loamy in other places, the scraper is specially designed to meet the different kinds of land, so as to be drawn thereover, with the plate either about at right angles to the surface of the road or sloping with reference to the said surface, according as required. The device is a rigid structure, and the different positions thereof are obtained by reversing the implement.

A further purpose of the invention is to lighten the draft to an appreciable degree and to facilitate the handling'of the implement. These results are attained by having the scraper of light and compact construction and composed of the fewest number of parts possible.

Further objects and advantages are contemplated and will appear in the course of the following description, reference being had to the accompanying drawings, in which- Figure l is a perspective view of a roadscraper specially designed for edecting the ends of this invention. Fig. 2 is a side ele Vation, the near runner or side piece being removed, showing the scraper in position for operating Aupon stiff l land, the dotted lines illustrating the device turned so ,as tofree it from accumulated earth. Fig. 3 is a view similar to Fig. 2, showing the. implement reversed for operation upon light and loamy soil. Fig. 4c is a rear perspective view of the scraper.

In the preferable construction the plate is composed of a series of wooden slats and is deflected on a line parallel with and intermediate of its longitudinal edges. Metallic strips or blades 2 and 3 are applied to the longitu-` dinal edge portions of the plate and sustain the wear when the implement is drawn over the road or surface to be graded. Side pieces 4 are secured to the ends of the plate 1 and constitute runners and also serve to prevent the earth gathered by the plate from escaping over the ends thereof. These side pieces are of a length corresponding to the distance between the longitudinal edges of the plate, and their terminal portions are rounded and serve as rocker-bearings for the implement to turn upon when thrown from an operative position, so as to free the plate from the earth gathered in advance thereof. The plate 1 is secured to the rear edges of the side pieces 4, and strap-irons 5 encompass the side pieces and the end portions of the plate 1 and serve to secure the parts against separation when subjected to abnormal strain. These strapirons also Vreinforce the side pieces et and receivethe wear incident to the implement sliding upon the runners.

Y The foot or tail board (3 is rigidly attached to the edge portion of the plate 1 and extends IOO lIO

for operation upon stiff or light soil provided l trails upon the surface.` A wear-'plate Slis applied to thel bottom side ofthe rear en'd portion of the tail-board and sustainsl the wear when the implement is in service When the' implement is placed with the tail-v board lowermost, the plate 'loccupies a position about at right angles to the surface off the road, whereby the scraper is best adapted for Voperating uponjloose and light soil.'v In` either position of `the implement the device can bey turned so as to free it from the earth gathered in front ofthe plate l, asclearly inv dicated by the dotted lines in Figs. 2 and'."`

The draft attachment 9, to Which the'aniy -mal is hitched, is of bail shape and is connected to the plate l about medially thereof. VStrap-irons ylOfare applied to the face of lthev plate l, and ycorresponding strap-irons ll are applied to the' rear side of the saidvplate.

`Thesestrap-irons arev4 in coincident relation and are secured together and to the plate V,by rivets or other fastenings passing throughv Y correspondingopeningsin theparts connected thereby. 'The leyebolts l2 or like means for u coupling the draft attachment to the implement pass through registering openings of i the plateand the front and rear strap-irons, l

and the latter serve to distribute'the i strain throughout the extentof the plate, thereby p decreasing the chances for crippling the implement .When strikingr a stone,vr root, or like `unyielding obstruction. l K Y Having thus described the invention,wha't is claimed as new isy l. A reversibleroad-scraper constructed with the foot or tail board adapting th'e said scraper to be held in either -a sloping ora right-angularposition with reference to the surface by means of the yfoot or tail board, substantially as set forth.

.I Ina reversible road-scraper, the :combination with the plate havin grelatively upper and lower scraping edges,'of a tail-board rigidly connected to the plate and located about in the plane Vof an edge thereof and adapted Y tohold the scraper in either a slopingor rightface, .substantially as set forth. K

3. In 'a reversible road-Scraper, a plate providedwith relatively upper and lower scrapangular positionwith yreference to the sur- Ving edges, and having a tail-board about in the plane lof one of its edges, and side `pieces applied to the face of the plate at the ends thereof and ofl a length corresponding tothe ldistance between the scraping edges of said plate, said side pieces constituting runners andhaving their end portions made rounding to provide rocker-bearings, substantially as described. v4.Tl1e herein-described reversible roadscraper comprising l`a plate deflected on al medial line andha-viiig' relatively upper and lower scraping edges, side pieces secured to the end portions of the plate and of a length corresponding 'to (the distancefbetween the saidlscra'ping edges and having their end portions rounding to providerockerbearings, a

draft attachment applied at a medial point to said plate,`and a tail-board rigidly attached to an edge portion of the plate and adapted to holdsai'd plate in either'a sloping or in a right-angular position with reference to the surface being graded, substantially as specified..

` In testimony whereof I affix my signature in presence of two witnesses. v
